RADIATOR.

Application led September 21, 1923. serial No. 664,083.

My invention relates to certain new and useful improvements in radiators such as are especially adapted for use with internal combustion engines in automobiles and the like;

5 it particularly has for its object to provide a radiator of such construction that it will be proof against leaka e due to freezing and of such construction t at it may be quickly and easily repaired if and when necessary.

Another object of the invention is to provide a means to prevent the radiator blowing up by an over-amount of steam pressure enerated within the same should the overow or vent pipe for any reason become clogged.

Again it is an object of the invention to provide a radiator whose tubes can be standarized and made or tubing sections of long lengths from which the desired length piece can be cut to fit any water radiator which may be in need of repair, by simply selecting from a few stock tubes a tube of proper width and thickness.

In its general nature the invention comprises a radiator of the usual form consisting of top and bottom water tanks united by water tubes spaced apart for the passage of air, the top and bottom water tanks, however, being provided with wide openings opposing one another and surrounded by short flanges to which the water tube sections may be soldered; each water tube section is of approximately rectanglar cross section and so formed as to be laterally expandable in the event the water within the radiator freezes. The water tube sections are spaced apart by corrugated lins held non-rigidly in place and adapted to give when the water tube expands so as to permit the expansion ofthe water tubes due to freezing of the water, the tins being of sufficient resiliency to assume their original form when the expanding tubes contract again on thawing out of the ice.

The radiator also includes a neck which communicates with the water tank through a perforated partition or strainer whereby solid matter which would tend to clog the radiator is prevented from entering the water tanks and tubes, and the neck is also provided Witli a cap in which is provided a vent valve to relieve steam pressure.

In its more subordinate nature the invention furthermore resides in those novel features of` construction, combination and arrangement of parts, all of rwhich will be first fully described, then be specically pointed .out in the appended claim, refer- .ence being had to the accompanying drawmo's, in which v tFugure 1 is a perspective view of a radiator embodying my invention.

Figure 2 is a rear elevation of the same.

Figure 3 is a horizontal section of the radiator.

Figure 4 is a the water tubes.

Figure 5 is a perspective view of one of the fins.

Figures 6, 7, 8 and 9 are respectively diagrammatic horizontal sections of modified forms of the radiator embodying my invenion.

In the drawings, in which like numerals of reference indicate like parts in all the figures, it will be seen the radiator is composed of the usual top water tank 10 and bottom water tank 7 united together by the vertical water tubes which constitute one of the essential features of my invention. The water tanks have opposing openings surrounded by short lianges 8 and l2 to which the flanges 5 of the water tubes are soldered. The flanges of the water tubes are made of sufficient Width so that when the tubes are all soldered in place the opposing openings of the top and bottom tanks will be closed perspective view of one of by the flanges of the tubes which thereby form a covering for such openings.

Each tube comprises av front wall 1, a back wall 2 and side walls 3, the metal of the side walls being folded inwardly, as at 4, to form vertlcal water passages in each water tube and to allow the water tubes to expand when the water freezes. Each tube also includes the end flanges 5.

In building up my invention or in making repairs the langcs 5 are soldered together and to the top and bottom water tanks by solder as at 6, using an ordinary fork solder iron.

9 designates the cold water outlet to the bottom tank 7 and 22 designates the hot water inlet to the to water tank 10. 11 is the neck of the tanlr 10 through which water is introduced into the radiator, the same pass ing through the perforated bottom 13 of the neck 11.

The vent pipe 14 also passes through the bottom of the neck (top of the top tank 1Q) and passes down to the bottom o the radiator as in the usual practice.

The neckll is provided with the usual cap 23 in which, in m present invention, there is rovided a ba check valve 15 which, while allowing air to enter, will open against pressure from within the radiator to blow oil steam accummulations and revent the radiator expandin in the event t e vent pipe becomes clogged or any reason.

16 designates the fins which are placed between adjacent water tubes. These fins are preferably of the conventional type having air holes and deilectors 17 to break up the air currents and deflect the air against all exposed surfaces of the water tubes for cooling purposes. These fins are not soldered in place as is the usual radiatouractice, but are of a len h less than the hei ht of the tube an are held in place only y retainin flanges. They are of sufficient yieldabi ty or resiliency so that when the tubes expanden the water freezing the fins will be compressed accordingly without exerting undue resistance to the expansion of the tubes and after the tubes re-assume their initial position on thawing, the fins will likewise assume their normal positions.

In order to hold the fins in place against edgewise or front and back movement, the back of the radiator may be provided with straps 18 that are soldered to the radiator tubes and the front of the radiator ma be rovi'ded with a wide mesh screen 19 w ich 'kewise may be soldered at intervals to the tubes or which ma be held in place by the usual radiator shel covering not shown (this is a coverin .usually placed over the radiator to give nis to the appearance of the same). 20 are corner braces for the overhang of the top water tank, the corner braces being soldered to the side plates 24 that connect the to and bottom water tanks together, the si e plates 24 having ears 25 soldered to the to tank and side brackets 21 have portions 6 and 27 projecting under and soldered to the bottom tank. 21 designates the side brackets which are secured to the plate 24 by bars 24* and by which the radiator is mounted on the chassis frame of the automobile.

It is to be noted that the back straps 18 include cross members which are soldered to the flanges of the side plates 24 and serve to brace the radiator against lateral distortion.

In the practical use of my invention if a radiator tube becomes damaged it is only necessary to remove the screen 19 and apply a hot fork soldering iron to the anges 5 after first removing the tins 16 at each side place of the old one and soldered by the useof a fork soldering iron as before, after which the fins 16 are replaced as is also the screen 19 and the radiator will be ready for use.

As shown in Figures 6 to 9 inclusive the invention may be a plied to different types of radiators than t e one shown in l 4 and 5. The staggered tubes form abutmenta for one edge of t, e fins while the screen and cross braces form the respective abutments for the other edges of the fins to hold the same in place `as will be clear by reference to Figures 6 to 9 inclusive.

From the foregoing description, taken in connection with t e accompanying drawings, it is thought the construction, operation and advantages of my invention will be clear.

Attention is however called to the fact that with my construction ofrsdiator the water flow is straight from the top reservoir down to the bottom reservoir, thus the passages of the tubes, being of relatively wide form, offer little or no chance for clogging in the event that sediment gets into the tank; the provision of the apertures 13 in the top of the top water tank, i. e. in the bottom of the neck, acts as a strainer, however, prevent sediment entering the radiator when illling the same and in that way reduces the liability of clo gin due to the sediment.

It will a so e noted that the fins are punched in such way that the air paing throu h between the tubes is ca t and deflecte against the sides of the tu thus increasing the cooling qualities of the radiator. The fins also serve as springs between the water tubes so that if the water freezes and pushes out against the fins they will be pushed back when the ice in the tubes thaws out again.

What I claim is.:

In a radiator, a top and a bottom tank having opposing portions each provided with an opening, the opening in one being o? site the o ening in the other, a series o t water tu s of substantially rectangular cross section having flanges at each end, those at one end of a tube adapted to lie in contact with those of the same end, of adjacent tubes and constitutes closures forsaid openin and spacers for said tubes, means for e acting a water seal and actin as a holding instrumentality between thea jacent flanges of said tubes and the tank whose opening is closed thereby, said tubes adapted lll lll

Lemans 3 to bellie outward when water within them said fin plates when seid restraining means freezes, n plates located between the tubes, is removed being themselves bodily slideble said lin lates being corrugated and of an through the front of the radiator for re- 10 over-all ength slightly less than the dismoval or replacement without disturbing the 5 tance between the top and bottom flanges of tubes, substantially as specified.

the tubes, and means restraining sald fin plates against front and back displacement, JOSEPH BARNEY HENDRIX.
